I believe this is a Universal Fire Arms M1. Mint condition! Looking into the M1 information on the web, this rifle looks to be a 1960's or 1970's model. ? There is a cheek rest on the stock and a four digit serial #. A "PI" stamped on the rear sight...what looks like a "UI" stamped under the sight. No other markings except the 30Cal. stamp on the barrel...
Any help steering me to the origin of this awesome rifle is appreciated. my best info has come from : http://www.bavarianm1carbines.com
